My point: at face value your argument fails. I mean you're taught many things in life by your parents, by your teachers etc., yet you believe them without question.
Okay, just no. I can tell you right now that this is not true for everyone, and it is especially not true for me. When I was a kid, whenever my parents laid down the law in our house, I would say "okay, but why?" It wasn't about being rebellious, I genuinely wanted a reason for the rules and boundaries I was to follow. Seeing as my parents were good enough debaters to convince an 8-year-old, I often followed those rules, too. When I was 5, I went to a Christian day-care, and was, inevitably, taught the tales from the bible as if they were scientific facts. As I was 5, I had nothing to base my standards on, and so I bought that. Just like Christopher Columbus sailed across the Atlantic, so had Jesus walked across a lake. But I still had questions. I once asked them what came first, Adam and Eve or the dinosaurs. When they couldn't answer a question as simple as that, and I had already seen fossils first-hand, the bible lost credibility, even to my as of yet not quite mature mind. In fact, I ended up getting yelled at for asking questions, which prompted even more scepticism.
Like you're taught by your teachers that, say, Chris Columbus discovered North America, how do you know? You weren't there, someone could have falsified history.
I actually know that he was not the first westerner there, because I've read about Vikings crossing the Atlantic in search of good timber and food. That's the thing about history, as well, any document sufficiently old has to be taken at least a bit seriously until you can prove otherwise, but we actually do read those documents with a critical eye. It's just that it's unlikely that the royal court of Castile just made up the tales of a man who crossed the the ocean in search of India, and found a new continent exactly where one appears to be in this day and age.
Or how about that you were taught that CD player reads a CD by pointing a laser on little pits that contain the data. How do you know that's true? Have you taken apart a CD player while it's running or put a CD under a microscope? No? You choose to believe what you were taught.
No, I've used CD's to experiment with laser interference, though. I've also taken apart CD players and used the lasers. Even so, that's not even the point. We know that all CD player manufacturers tell us that their CD players work that way. We know that the science textbooks tell us that CD players work that way. We know that the technology exists to do this. Why would we disbelieve something so mundane? Should we just believe that it's all a conspiracy because we can? Things like banning homosexuality(which the bible doesn't, it only disallows gettin' freaky) are illogical with the knowledge we have today, because we know that homosexuality never hurt anyone(excepting, of course, religious fundamentalists who stone homosexuals to death), and therefore, there's reason to disbelieve or question. You're talking about a set of moral laws from the bronze age. Do you know of ANYTHING else that we still have not improved upon that they had in the bronze age?
One last time: at face value you're argument fails.
I think your argument fails at face value.
